Eddy-Current Probe Scaling and Gap Voltage Validation
Probe scaling adheres to the 200 mV/mil sensitivity standard for 8 mm eddy-current transducers. Gap voltage validation targets a nominal -10 VDC bias when the probe tip is positioned at mid-linear range. Rotor dynamics measurements require verification of probe standoff to ensure linear response across radial vibration excursions. Cross-talk suppression is achieved via shielded coaxial cabling and connector grounding at the DIN rail interface.
Frequently Asked Questions
Q: Can this sensor be hot-swapped on a live DIN rail bus?
A: No. Power must be removed prior to removal or insertion to prevent transient voltage spikes damaging the conditioning electronics.
Q: Is calibration required after replacing a probe in the 5.0 m system?
A: Only if the replacement probe has a different scale factor; otherwise, the system remains calibrated within the 3300 XL interchangeability specification.
Q: What is the expected gap voltage drift over full operating temperature range?
A: Drift is limited to less than ±2% of full-scale output between -52 degC and +100 degC under stable mechanical mounting.
Field Installation Guidelines
Install the sensor on a secure 35 mm DIN rail, ensuring proper seating until locking clips engage. Use only Bently Nevada–approved extension cables to maintain total system length of exactly 5.0 m. Ground shield terminations at the sensor end only to avoid ground loops. Verify gap voltage before commissioning by measuring the DC bias at the monitor input terminal. Tighten connector protectors fully to maintain environmental sealing in hazardous areas.
